Product Description

Property

CAS No.: 2622-14-2 Formula: C18H33P Molecular Weight: 280.42800

Description

Tricyclohexylphosphine is the tertiary phosphine with the formula P(C6H11)3. Commonly used as a ligand in organometallic chemistry, it is often abbreviated to PCy3, where Cy stands for cyclohexyl. It is characterized by both high basicity (pKa= 9.7) and a large ligand cone angle (170°).
Important complexes containing P(Cy)3 ligands include the 2005 Nobel Prize-winning Grubbs' catalyst and the homogeneous hydrogenation catalyst Crabtree's catalyst.
Grubbs' catalyst (first generation) Crabtree's catalyst
